What size adapter for Nikon L340?

I'm looking to get a macro ring light for my camera but I'm not sure what size adapter I need for it. Does anyone happen to know?

Also, does anyone know if I can use any sort of shutter remote with this camera?

Does 105mm Macro lens take much better pictures than a 40mm Macro lens?

I'm sorry for the silly question, is that I'm a very beginner in photography, and after purchasing a Nikon D5300 last July, I have been practising taking macro pictures with a 40mm Micro Lens, and sometimes use reversed kit lens to take super-macro photos…
I like the lens I have, but I was looking at the prices of that 105mm macro lens, and wondering if I could make better macro photos with that… Is it worth? The price is spicy… It has to be worth lol…

How to fix a camera lens with water in it?

I have recently, way too recently, bought a digital camera (Nikon S7000) and got water into the lens.

I don't mean dropped the camera into water, but when I went outside in the snow to take photos yesterday I slipped and a bit of snow went on the lens.

I have wiped this off with a lens wipe and the outer lens looks clean, with no smudges, but when I try to take photos they are blurry.

Could the water/snow have gotten into another layer of lens or something?
And how can I fix it? Does it need to be sent a pro or do I need a replacement?

As you can tell I'm not at all a camera expert, I know nothing about cameras, so any help is appreciated.

What camera is best for concert photography?

I don't care about the size because i have been using Canon EOS REBEL T3i at concerts already

Does this make any sense?

I've upgraded from dx to fx, including going from the Nikon D7100 to the D750, freaking awesome camera!

Anyway, the specs said that the 750 had nearly the same
Burst rate as the 7100, about 6.5 fps

Well, I'm getting Way more than that. I put it on continuous high, hold the shutter button and get off a good 12 shots in rapid machine gun succession before the camera slows down.

Same sandisk extreme sd card as well

I put the same sd card in the 7100 and nowhere near as good

So, what's the deal?

No, I'm not complaining, lol just the opposite, but I'm just wondering what else could explain this?

How much should I sell my Nikon D7200 (w/18-140 lens) for?

I'm thinking about selling my Nikon D7200 with an 18-140 kit lens included. I paid roughly $1800 for it, during a boxing day sale this year. I bought the camera in early December and I've used it a fair bit since then. I've taken very good care of the camera and it's in excellent condition. I thinking of selling it to help pay for my tuition this semester, so I'll need to be able to get a reasonable, but good price for it.

I need some advice on Water Resistant, Long-Term camera bags?

I plan on traveling for the next few years throughout the US and Canada, and I need a camera bag that's going to get me through it all. I'll be camping, hiking, swimming, kayaking, spelunking, etc.

Size: I'm a small person (5'3 at 120 lbs) so one of my biggest concerns with shopping for these bags is getting my spine crushed. I have a Nikon camera, 4 lenses, and a tripod. I would very much like to be able to fit a Macbook in the bag when needed, and other things like snacks/sunblock. But I can't deal with a behemoth bag. I'd like something with good structure so it doesn't hurt my back while hiking.

Functionality: I need the best in water resistant materials. I'd rather pay $400 for a bag once than replace thousands of dollars worth of gear. I'm not careless with my gear in the least bit, but I don't want to take chances. I love how the Lowepro Dryzone 200 even FLOATS, but that goes back to my first concern of being too much of a burden to carry. I need something that will last and doesn't scream "I'm full of $$$" (another reason why I lost interest in Lowepro Dryzone 200).

The one I'm currently looking at is Whistler BP 350 AW by Lowepro.

It looks pretty good (size-wise), but I'm not sure it's as watertight as I need…

Is a Canon G7X good enough for portraits (on a scale of 1-10)?

If not which one is? (budget:$500, it has to take video as well)
